Tens of thousands of people from around the world threw tones of ripe tomatoes at each other Wednesday in an annual food fight that leaves the eastern Spanish town of Bunol covered in red‘pulp''（果肉）．
More than 40，000people，including many visitors from Australia，Britain and the United States，took part this year in the food fight known as the"Tomatina"，now in its 64th year，a spokeswoman for Bunol's town hall said．
They were provided with over 100tones of tomatoes by the town council for the battle which lasted about one hour and left participants covered in pulp and standing ankle-deep in red mud．
Many men were shirtless while others wore old clothes，hard hats，'goggles'（护目镜） or protective plastic sheets．
Shopkeepers put up huge plastic covers on their store fronts or boarded them up to protect their properties from the sea of red'mush'（糊状物）．
After a battle，municipal workers and local residents used giant'hoses'（水管，软管） to clear the walls and streets of the tomato pulp in just half an hour while the participants headed to a nearby river where temporary showers were set up．
The event cost the town of some 10，000residents 28，000euros （40，000dollars） to practice the battle，Spanish media reported．
The"Tomatina"is held each year in Bunol，located in a fertile region some 40kilometers （25miles） north of the coastal city of Valencia，Spain's third-largest city，on the last Wednesday in August．
The origins of the event are unclear although it is thought to have its roots in a food fight between childhood friends in the mid-1940s in the city．
It has grown in size as international press coverage brought more and more people to the festival．
